Hello,

I have an AMD radeon pro W9100 in a Sonnet EGFX650W on a MBP 2018 Mojave and i would like to have 6  x (1920x1080) outputs working.

I have 6 Startech minidp to hdmi active adaptors.

As my screens are far away i convert the HDMI to SDI with microconverter from Blackmagic.

When i add the 4th monitors i get blinking blue flash and color space problem.

How much active adaptor should i use....

Is there any document i could read to understand this system on clocking or at least any info on how to get 6 outs working clean with this card.

Thank you

Best regards 

Hubert

Hi Hubert,

6x HD displays should be working just fine. I suggest you bypass the HDMI-SDI converter and connect the monitors directly to your WX9100 to test.

Hello fsadough,

I'm not able to connect them directly, I need to go thru converters.

Everything is ok as long as i'm under 4 outs and this with the same converters...

I tried off stage with 6 Barco 2301 RHDM (only SDI inputs) and I had the same problem, some blue flash and sometimes color space error like sendind uyvy instead of argb or something like that.

I'm going to play with 4 PTRZ12K and 2 PTDZ16K from Panasonic, I need to make it run smoothly.

So I'm looking forward about clock problems. How many active adaptor do I need to run these 6 outs...

Logically it would be only 4 but i'm not sure. Are there any informations out there?

Do you know a place where i could get some precise informations about the clock systems?

FWIW : we had another install with a WX7100 (same box same computer) and the 4 outs worked like a charm with passive DP to HDMI.

Thank you

Best regards

WX7100 was running with HDMI-SDI converter?

Hello,

yes why is that "paranormal" :-?

[fsadough]

No, just needed a clarification if WX7100 was running on the exact same setup as WX9100. Send me a screenshot from Radeon Pro Settings => System => Hardware

I'm on OSX.14.3 Mojave.

Where can i find radeon pro settings?

As i said in my first post, the card is in a sonnet EGFX650w box and i only have an icon telling me that the card is connected, no accessible parameters...

The box is connected via an usbC/TH3 cable.

I use the software Millumin to drive my show.

Each output of the card is connected via a Startech miniDP to HDMI active connector to a Blackmagic micro converter HDMI->SDI and then it goes directly to the input of the screens or to the input of the video projectors.

HTH

Thank you

You can contact Sonnet to clear the compatibility.
